How secure is the PocketKey’s encryption, can it be broken?

The PocketKey uses stronger encryption than any payment method ever created, and it cannot be broken.

Each PocketKey is pre-loaded with more than 500,000, 256-bit, randomly generated encryption keys. Each encryption key is used only once, and then discarded. The encrypted data is also scrambled, and signed with a private key known only to the device.

This is known as a form of One-Time-Pad encryption, and it is simply the strongest encryption possible. Most cryptographers consider this the only “Perfect” form of encryption, since it can never be broken. Even with access to millions of computers and years of effort, not a single fake payment could be generated by a thief.
